This transaction set provides terminal and cargo information related to port operations and freight handling. Carriers, freight forwarders, and terminal operators send the 319 to communicate details about cargo being managed at terminals, typically in response to inquiries or as part of standard terminal reporting procedures. The BA2 (Beginning Segment for Cargo Terminal Information) establishes the transaction’s purpose and scope, while the CD1 (Cargo Detail) segments convey specific information about individual shipments or cargo items being processed at the terminal. The message is structured simply, with the ST header and SE trailer bracketing the operational data.

For example, Global Port Services receives containers at its container terminal in Los Angeles and needs to notify shipping lines about the cargo being warehoused. Ocean Freight Logistics, the carrier, receives a 319 transaction set from Global Port Services containing multiple CD1 segments—each detailing a shipment’s destination, weight, hazardous material status, and terminal storage location. This allows Ocean Freight Logistics to track its cargo through the terminal and coordinate pickup with customers, ensuring accurate inventory management and timely shipment release.
